The standard Trangia pans are cheap and perfectly good. Maybe not quite as big as you need, but, as Pete says, they do other sizes byond the standard 27 and 25 cooksets.
Titanium has its proponents (and I have three Ti pots...), but it's no lighter than an equivalent aluminium pot, and, being thinner and conducting heat at 1/10 the rate of aluminium, it is prone to hotspots. The WindPro uses a wide burner IIRC, so shouldn't exacerbate this problem like small burner-head stoves.
The supposed causal link between Al and Alzheimer's has been disproved, so that's one fewer worry...
I use plastic cutlery apart from a tiny little paring knife for cutting ingredients up. Current favourite is a little silicone spatula I found in TKMaxx (Joie! MiniBakey set).
I'm pretty sure the Vargo pans John linked to are Al with the same 'titanium' non-stick coating used on the Primus. I've yet to get to the bottom of the titanium content (or otherwise...) on the non-stick coating; it seems to me to be just another name for a proprietary PTFE coating, like 'Platinum'. I do wish companies wouldn't abuse element names in this confusing way.
